Spray was the sailboat used by 19th-century Canadian-American seaman and author Joshua Slocum during the first solo circumnavigation of the Earth. Slocum departed Boston Harbor in the 36-foot-9-inch (11.20 m) vessel on April 24, 1895 and returned to Newport, Rhode Island on June 27, 1898, becoming the first person known to have sailed around the world alone.

Aluminum and aluminum alloys are used both in sheet form for all-metal hulls or for isolated structural members. Many sailing spars are frequently made of aluminium after 1960. It is the lightest material for building large boats (being 15–20% lighter than polyester and 30% lighter than steel).
The rigid buoyant boat (RBB) is a light-weight but high-performance and high-capacity boat. Based on the concept of a rigid-hulled inflatable boat (RHIB), it has a tube/sponson manufactured from a solid material such as moulded polyethylene or aluminium which is much more robust than the fabrics commonly used.
It features a hull made of layers of carbon fiber, a foam core, and an outer layer of Kevlar for additional strength. It was constructed and launched at the Hodgdon Yachts' East Boothbay facility. The MAKO is lighter than the current Mk V. [ 5 ] The Office of Naval Research funded the prototype "to compare the properties of composite ...

A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along ...
